| Name and quarry location: | Bigio antico, bigio morato, locality unknown |
| Geological description: | Grey-brown bioturbated limestone with a few mollusc fragments. Note white coarse-grained spar-filled cavities and fractures, and abundant stylolites. The surface is waxed and polished. |
| Comments: | Nothing is known about where this stone is from. Superficially it looks like the finely veined formed of portoro ('portoro macchie fine') but the yellow in the stylolites is filler/polishing compound, not a feature of the stone. |
